Title: Hydroisomerization of wax or waxy feeds using a catalyst comprising thin shell of catalytically active material on inert core
Inventor: CODY IAN A
IPC: B01J23/42
Filed: 1992-11-13
Abstract: Wax and waxy feeds are hydroisomerized by contacting the wax or waxy feed under isomerization conditions with a catalyst comprising a thin outer shell of catalytic material bonded to an inner core of catalytically inert material. The catalyst is made by coating a catalytically inert core such as alpha alumina, with a thin layer of finely divided catalytically active material in a slurry of colloidal boehmite/pseudo boehmite then calcining to convert the boehmite/pseudo boehmite into alumina which bonds to the inert alumina core.      Catalysts made by this technique for hydroisomerization contain an outer shell of platinum on fluorided alumina on an inert core of alpha alumina.

Title: Method of washing an upflow filter and filter bed employed in said filter
Inventor: KIM ANNABELLE
IPC: B01D29/62
Filed: 1991-08-23
Abstract: A method of washing an upflow filter (12) between service runs employs a filter bed (26) having a non-buoyant particulate filter layer (56) through which influent to be filtered is directed in an upward direction, and through which liquid employed in the washing operation is directed in an upflow direction. A two-stage washing operation includes the steps of first directing a combination of air and liquid in an upflow direction through the filter layer (56) with the velocity of the liquid being less than the minimum fluid-ization velocity of the filter layer (56), for disrupting only some floc retained in the filter layer during a previous service run, and thereafter directing only liquid in an up-flow direction through the filter layer at a velocity less than the minimum fluidization velocity of the filter layer for removing disrupted floc from the filter layer while leav-ing some floc attached to said particulate media of the filter layer. The process most preferably is carried out with a filter bed (26) including a coarse, particulate media flocculation layer (52) for distributing the flow of influent and promoting flocculation.

Abstract: An electronic delay circuit for firing an ignition element.  The delay circuit includes a  capacitor which stores electric energy supplied from an electric blasting machine, an oscillator generating a clock pulse train, a circuit for over-exciting the oscillator, a counter which counts clock pulses of the clock pulse train, and a circuit for maintaining a reset state of the counter for a predetermined time period after the electric energy is supplied.  The counter produces a trigger signal when it counts a predetermined number of the clock pulses, and the electric energy stored in the capacitor is discharged to the ignition element.  Since the oscillator enters into the steady state in a very short time by the over-excitation, the delay circuit has large resistance to external noise.

Abstract: ABSTRACT OF THE DISCLOSURE         Ultra fine powder is stored in a pneumatic transportation tank 20, and is discharged to a transporting conduit 23 while being fluidized by the pressurized air fed through a fluidizing air port 24.          The ultra fine powder is fed to a weigher 30 provided at the other end of the transporting conduit 23, at which the weight of the transported ultra fine powder is weighed by a load cell 31.  After the weighed value reaches 90% of a predetermined value, the fed amount of the pneumatic transportation air is reduced, and a bypass regulating valve 38 is adjusted to thus decelerate the transportation.  When the weighed value reaches 100% of the predetermined value, the discharge of the ultra fine powder to the transporting conduit 23 is stopped.  This method and the apparatus enable the storage, quantitative batch transportation and automatic weighing of the ultra fine powder such as silica fume.

Abstract: A method and apparatus for controlling the execution of image processing operations carried out on an array of image signals, the specific operations having been identified by a plurality of predefined windows.      The windows are divided into a plurality of regions, the boundaries of which correspond to transitions from one window region to another. Each region defines an exclusive region within the array of image signals, and the image processing operations to be applied to the signals within the boundaries of that region. The image processing operations are selected by decoding an effect data word that is assigned to each pixel and which follows the pixel along the image processing path. The bits within the effect data word are not assigned individual significance which allows the effect data word, in most cases, to maintain the same bit length even though additional image processing procedures or modules have been added to the image processing path. The apparatus is designed to efficiently manage the identification of regions while minimizing the bit length of the effect data word used to identify the image processing steps.    The apparatus also provides flexibility of architecture design resulting in more efficient expansion of functions and easier modifications to existing functions.
